Despite the advent of modern neuroimaging, electroencephalography (EEG) has retained its usefulness for the evaluation of brain masses and headaches, and it is indispensable for the proper management of paroxysmal episodes and for the surgical evaluation of intractable epilepsy. Recent research has dug up more treasures concerning EEG (eg, ultrafast and ultraslow potentials, direct current potentials, and high-frequency oscillations), and there are ongoing attempts at increasing the accuracy of source localization and automated seizure detection. Moreover, intraoperative neurophysiologic monitoring has become, to a large extent, a part of the EEG specialty. Other emerging techniques, such as magnetoencephalography, transcranial magnetic stimulation, and the brain-computer interface, have deep roots in EEG. Thus, the modern electroencephalographer has much more to master today than in years past.
